The girl had suffered over 95 percent burns and was fighting for her life at Safdarjung Hospital in Delhi following the incident that occurred on Monday in Tigri village in Greater Noida West.

The girl died in the wee hours, a senior doctor said. The accused, aged 18 years, has been taken into custody. He was a neighbour of the victim's family and, according to her father, had become friendly with her.

The police said the youth allegedly went to the girl's house and met her on the roof where he raped her and set her ablaze. He then fled the spot.

The incident, which occurred on the eve of International Women's Day, is yet another in a chain of crimes against women in Delhi and the National Capital Region (NCR) zone, where the Nirbhaya gangrape case of 2012 had led to nationwide outrage and a revision of rape laws.
